IMPROVEMENT IN GRAIN- IDRIERSv The Schedule :referred to in theseLetters Patent: and making part of the same.

To all twhom it may concern:

Be it known that I, JEROME J. MUNGER, of' Syraeuse, in the county ofOnondaga, andV State of N ew York, have invented a new and usefulImprovement in Grain-Driers; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a central vertical section of my invention, and

Figure 2 is a side elevation of the same, with the outer wall or shellbroken away near its foot.

Figure 3 shows a bottom view of the discharging# ung.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to new and useful improvements in grain-driers,whereby an economical and eiiieient apparatus is obtained, ashereinafter explained.

In the accompanying drawings- A is an inner wall, which is closed atitstop by a cover, a., and is perforated from the top down as far as C is aperforated outer wall or shell, and has a spout, c, at its top, forreceiving the grain.

F is a iiatring, which serves as a fioor for the dryingchamber e c, figll, and has an opening, f, for discharging the grain from the chamber e.

This ring is provided with cogs on its lower face, and is rotated bymeans of a pinion, h, so that the opening, j, may be constantly rotatedunderneath the grain in the annular drying-chamber e, and the graindrawn evenly from all sides of said chamber. l

The discharging-ring F may be supported on antifrictiou rollers, so asto run with the least amount of resistance, if desired.

The inner and outer walls A C extend downward below the discharging-ringF, and form an annular chamber, e', below said ring; -and in thisannularI chamber is placed an inclined floor, i, so that all graindischarged through the ring is collected to one side, at thedelivering-spout I, by sliding down the inclined door or chute 'i of theannular chamber e.

The lower part of the inner wall or cylinder A is occupied by a furnace,B, having an ash-pit, J, and a flaring conical top, b.

k is an arch or door-way through the walls A C, giving access to thefurnace.

lts operation is as follows:

A fire is lighted in the furnace B, and is supplied with a smokelessfuel, like anthracite coalor coke, and grain is then run into the spout'e until the annular' lrying-chamber c c is filled. The ring F is soonset in motion, and is kept constantly revolving, and withdrawing grainfrom all parts ofthe fioor of the chamber as the said ring revolves andcarries the discharging-orifice f around underneath the grain.

The orifice j' of the ringl F is provided with a sliding gate, (1, fig.3, for closing said orifice j, or for vregulating itsdischarging-capacity, as desired. By this method of withdrawing thegrain from chamber e, the action is made very even and regular, theagitation being the same in all parts of' the chamber, and the grainpassing through on all sides ofthe chamber with a uniform velocity.

The heated air from the furnace passes up and is diffused throughout thechamber A A (t, and, passing through the perforations in wallA, goesthrough the grain in chamber e e, and, taking moisture from the grain,escapes through the perfbrations in the ont wall C C. By these means, Iproduce a drier for grain Which'is efficient and economical in itsaction, and is also simple in its construction, and not liable to getout of order.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The annular chamber e e, the inner and outer walls of which areperforated, the revolving discharging-ring Ff, and annular helical chuteIi., passing through the lower part e of the chamber e, in connectionwith the furnace, B, all constructed and arranged substantially as andfor the purpose specified.

JEROME J. M UNGER.
